hey everyone, im new to the site and in need of help. i recently converted a 93 4cyl auto to 5.0 5 speed, just installed driveline and wont run worth a crap. engine runs extremley rich, wont idle except with idle screw all way in, hard to start when cold and when turn key on fuel pump runs but wont shut off and hear a hissing sound at fuel rail. engine mods are F303 cam, ported and polished heads with trick flow springs and 3 angle valve job, 1.6 roller rockers, gt40 intakes ported and polished, 70mm throttle body and egr spacer, 75mm mass air, cold air intake kit, pistons notched, underdrive pulleys, equal length shorties and off road x pipe. also installed new O2 sensors. also when try revving engine sounds like a delay box on the car. tried pulling codes but cant get any.i had a 88 gt that was used for the donor and bought a 93 gt 5spd wiring and computer from ebay. checked to make sure all sensors were connected and checked vacuum hoses and evrey thing is in place. any help would be greatly appreciated
